-Twenty four units were reliability tested and the following life test data were obtained:
-<center><math>\begin{matrix}
-   \text{61} & \text{50} & \text{67} & \text{49} & \text{53} & \text{62}  \\
-   \text{53} & \text{61} & \text{43} & \text{65} & \text{53} & \text{56}  \\
-   \text{62} & \text{56} & \text{58} & \text{55} & \text{58} & \text{48}  \\
-   \text{66} & \text{44} & \text{48} & \text{58} & \text{43} & \text{40}  \\
-\end{matrix}</math></center>
-Fitting the gamma distribution to this data, using maximum likelihood as the analysis method, gives the following parameters:
-::<math>\begin{align}
-  & \hat{\mu }=  7.72E-02 \\
- & \hat{k}=  50.4908
-\end{align}</math>
-Using rank regression on  <math>X,</math>  the estimated parameters are:
-::<math>\begin{align}
-  & \hat{\mu }=  0.2915 \\
- & \hat{k}=  41.1726
-\end{align}</math>
-Using rank regression on  <math>Y,</math>  the estimated parameters are:
-::<math>\begin{align}
-  & \hat{\mu }=  0.2915 \\
- & \hat{k}=  41.1726
-\end{align}</math>
